2 Claims, (Cl. 257-7192) This invention relates to a coolerconstruction. More particularly it relates to an arrangement by which adry storage tank is held within another tank containing a cooling uid,which dry storage tank is preferably easily removed for a variety ofrequirements.

In certain types of cooler construction it is the custom to place a drystorage tank adapted to contain articles to be cooled within anothertank, cooling uid and cooling coils occupying the space between thetanks. With such construction, the buoyant force of the cooling iiuidtends t push the dry tank up out o! the tank, and some means for holdingthe dry tank in place is required when this tank is not completelyfilled so that the weight o! the material being cooled will hold thetank in place.

An object of the present invention is to provide an improved colerconstruction.

A further object is the provision of a construction by which a drystorage tank is removably held within an outer tank containing a coolingfluid against the buoyant force of the cooling fluid.

According to the present invention a dry storage tank is positionedwithin an outer tank containing a cooling medium. The dry tank is heldwithin the outer tank by means of bracket members which extendrespectively from the two tanks and are secured to one another.

In the drawing:

Figure 1 is a view partially in section, showing the improved coolerconstruction;

Figure2 is a view taken along the lines 2-2 of Figure 1 with partsremoved;

the tank I3 along with the coils I4. The buoyant force of the duid tendsto push the tank I3 up out of the container l0, and, consequently, somemeans for holding the tank within the container is required.

This means includes a bracket formed desirably of sheet metal and havinga main portion 2l provided with an elongated slot 22 and base portions23 extending from opposite sides of the portion 2l and provided withslots 2l. This bracket 20 is secured, as shown in Figures 1 and 2, bymeans of its base portions 23I to the inner side of the tank I0 by meansof bolts v25 extending through -theslots 24. The point of securement ofthe bracket 20 to the tank I0 by means of the bolts 25 is immediatelybelow the top of the support I5 carrying the cooling coils I4, and theportion 2| of the bracket extends up over the Figure 3 is a sideelevation of a bracket adapted to be connected with the outer tank ofthe cooler;

Figure 4 is an end elevation of the same;

Figure 5 is a side elevation of a bracket adapted to be connected to theinner dry tank of the cooler; and,

Figure 6 is an end elevation of the same.

The cooler of the present invention includes an outer tank or containerI 0 having a filler of suitable insulation II. Resting within the outertank on supports I2 is -an inner dry tank or container I3. A pluralityofrefrigerating tubes Il secured to a supporting element I5 is. positionedin the space between the sides of the containers III and I3. A shield IBsecured to the container III, as at I1, covers the space between thecontainers.

container I3. During use of the cooler, cupies the space between thecontainer A cover I8 is hinged, as at I9, on the Ill so as to close itandthe dry tank a cooling fluid ocsupport I5.` There is also provided abracket 26, which has a main portion 21 provided witlLa circular opening28 and a base portion 29 provided with openings 30. 'I'he main portion21 has a groove 3l at its lower edge. The bracket 26 is attached to theouter side of the tank I3 by means of bolts or rivets 32 extendingthrough the openings 30, at least some of `the rivets 32 being below thetop of the support I5Xfor the coils I4. The portion 21 of the bracket 23extends out over the support I5 in overlapping-.rel tionship with theportion 2| of the bracket 20, an a bolt 33 and nut 34 secure thebrackets 20 and other. Similar brackets are provided at other pointsbetween the tank I3 and the. container I0. These brackets with theirbolt and nut connections serve to hold the tank I3within the containerI0 against'the buoyant force of the cooling iiuid in the space betweenthe tank I3 and the container III.

When it is desired to remove the tank I3 from the container I0 for anyreason, the cover I8 is opened, the shield I6 is removed, and the boltand nut connections are removed from thel0 and 55 buoyant force of thecooling medium. 'The simple to one anpositioned between the containersand extendina to a point near the open end of the containers, thecombination therewith oi.' means for holding the second container withinthe mst container against the buoyant force oi the cooling duid. saidmeans comprising a bracket secured to the inside of the first containeradjacent its open end alongside the device and extending up over thedevice toward the second container, a second bracket secured to theoutside o! the second container adjacent its open end and extendingtoward the nrst container up over the device toward thenrst container inoverlapping relationship with the i'irst bracket, and a member passingthrough the overlapping portions oi the brackets.

2. The combination specified in claim 1, the second bracket having agroove on its under side by means of which the securement of liftingmeans to the second bracket for removal oi the second container from thefirst container is facilitated.
